Results of the ZTEM survey indicate a number of targets, one of which was only partially on the company’s current holdings.

The area outside of the company’s holdings required the Bureau of Land Management (BLM) to approve the staking of additional claims.

BLM has approved this plan and the staking is expected to be completed in the next few weeks.

The additional claims being staked are northeast of the state of Maine property and immediately adjacent to the company’s current holdings.

The company said the geology shows an extension of the silver gold veins that were extensively mined in the 1920s close to surface on its Maine claims and the ZTEM has outlined the signature of a deep copper system.

Tombstone president Alan Brown said that this area is one of the company’s primary targets developed by the ZTEM survey, and has a signature of a porphyry copper or a resolution style copper deposit.

Tombstone is focused primarily on exploration and development of mineral resources.
